We used a Michelson-type interferometer to observe the waveform of the accumulated photon echoes in a 3,3′-diethylthiatricarbocyanine iodide–doped poly(vinyl alcohol) film. By Fourier analysis of the measured interferograms we obtained the shapes of the burned population grating and the phase grating in the sample. From the frequency distribution of the dye molecules, that is efficient for persistent spectral hole burning, we estimated the inhomogeneous frequency distribution of the 0–0 transition from S0 to S1 levels of the dye molecules in the poly(vinyl alcohol) film.
